SPINDLE.

Application filed April 10, 1885.

To aZZ whom it may concern.-

Be it known that I, LEVI \VILsoN, of the city and county of Providence, in the State of Rhode Island, have invented acertain new and useful Improvement in Spindles; and I declare the following to be aspeciiication thereof, reference being had to the accompanying drawings.

Like letters indicate like parts.

Figure l is a side elevation of myinvention with abobbin mounted upon the spindle. Fig. 2 is avertical longitudinal section of the same, with the spindle shown in elevation. Fig. 3 is a top view of the same. Fig. 4., is aside elevation of the shell and whirl. Fig. 5 is aside elevation of the spindle. Fig. 6shows the under surface of the cover of the oil-fountain. Fig. 7 is a transverse section on line m m of Fig. 6. Fig. 8 is a side elevation of the standard and oil-fountain. I

My invention relates to the bearings of spindles in thestandard of spinning-frames and the means for lubrication of such spindles therein, and has for its purpose the diminishing of the friction of the spindle upon the step and the more uniform and economical use of oil in the lubrication. This is accomplished by the pcculiar shape and relative position of the spindle shell and standard by which an air-cushion is formed in the upper part of the shell, above the standard, for the sake of supporting the weight of the spindle, and also producing upon the surface of the standard a continual upward movement of oil from a fountain into a reservoir in said standard, wherein the spindle rests upon its step.

I11 the drawings, A represents the bobbin; 13, the spindle; G, the spindle-shell; D, the whirl, and E the standard. The shell 0 has a central bore, as indicated by dotted lines in Fig. 4, the larger bore to receive the standard and the smaller here to allow the end of the spindle B to pass through. The standard E is furnished with an oil-fountain, F, cast in one piece with the standard, and has a screwthreaded end, by which it is fastened to the rail, and at its upper end a central bore,whose shape is indicated by dotted lines in Fig. 8.

The lower portion of the standard E, at its bottom, within the fountain F, has a slightly-enlarged diameter, as shown in Figs. 2 and 8, and furnishes there the lower bearing for the .ATIQIG' forming part of Letters Patent No. 340,848, dated April 27, 1886,

Serial No. 161,865. (No model.)

spindle-shell Q, to prevent the lateral play of the spindle when in position. A vertical or longitudinal slot, a, is made in said enlarged portion of the standard, as shown in Fig. 8. The fountain F has a cover, G, whose shape is shown in Figs. 2, 6, and 7, and having a central aperture, 1), through which the shell 0 and standard E extend. It also hasaslot, 0, upon one side, through which a bent pin, (1!, passes, which is screwed into the rim of the oil tank or fountain F. Thispin (1 turns upon its screwthread, and its bent head can be swung over the top of the whirl, thereby preventing the spindle and shell from rising upon the standard while revolving.

Having thus specified the several parts of my invention and their construction, I will proceed to describe the manner and advantages of its operation. I first pour a few drops of oil into the bore of the standard E and then seat the foot of the spindle therein, as shown. The shell 0 descends upon the standard E to the position shown in Fig. 2, and bears closely upon the lower portion of the standard. The air inclosed in the shell 0 is compressed by this movement, and forms an air-cushion, e, in the upper portion of the shell 0. This aircushion partially supports the weight of the spindle and shell, and so relieves the friction usually occasioned by the weight of the spindle upon the step. Less poweris therefore required to revolve the spindle, or the same power will drive the spindle at a greater speed than is obtained with spindles seated as usual. This air-cushion furnishes an elastic and soft bearing, conducive to easy and rapid rotation. Before seating the spindle, as above described, the oil-tank F ispartially filled with oil, which, working its way up the slot a of the standard E, is by the centrifugal force, aided by the expansion of the oil by the heat which is developed by the rapid rotation of the spindle, carried up along the standard and the interior surface of the shell until it reaches the top of the standard, and dropsinto the reservoirf to replenish the oil there. No evaporation of the oil takes place, as it is always in an inclosed space. It will be understood that in thus replenishing the upper reservoir, f, the oil is not lifted up bodily against the action of the aircushion, but simply spreads or is drawn centrifugally upward and along the heated opposing surfaces of the standard E and shell (3, not in a large volume, but as a mere film. This oil film, however, is sufiicient to replenish the reservoir f and keep the metal surfaces moist and well lubricated. The oil thus is distributed uniformly between the shell and standard, and keeps the reservoir fconstantly replenished, and all without any waste of oil whatever. I thus entirely dispense with the packing heretofore required. Such packing, as is well known, absorbs and wastes much oil, and does not distribute it uniformly for proper lubrication; and also by its snug contact in its confined position such packing causes niuch friction to drag or reduce the speed of the spindle in its rotation. In this way, also, I have diminished the friction of the working parts and still further enhanced the speed of the spindle.

It will be seen by examination of Fig. 2 that instead of extending the foot of the spindle into the standard far below the plane of the whirl D, as in the common construction, Iseat it upon the step within the standard in a line above the plane of the band-pull of the whirl.

I In the usual construction the power is applied at some distance above the seat of the spindle, and the leverage so produced has a dragging effect upon the spindle, amounting to a lateral friction. By my improvement this difficulty is wholly avoided. hen the foot of the spindle rests upon astep below the plane of the band-pull, the spindleis not easily centered in operation, because it is subjected to the constant strain of the band in one direction. The steadiness of the rotation. is injuriously affected thereby, and there is a consequent loss of power or diminution of speed. In my device the spindle, being seated above the line of the band, cannot be affected by the pull of the band, but simply rides upon the step as a well-poised load, and is entirely relieved of any lateral strain. The result is that I can attain a speed of rotation exceeding that of any spindle heretofore devised.

I claim as a novel and useful invention and desire to secure by Letters Patent 1. The spindle B, the centrally-bored shell 0, and the reservoir F, in combination with the standard E, fitting within said shell 0, to form an air-cushion, e, to partially sustain the weight of thespindle,substantially as specified.

2. The combination of the standard E, having slot to and oil-receptacles F f, the spindle B, seated within said standard above the plane of the band-pull of the whirl, the shell (1, havin g the whirl D, and which surrounds the stand ard E, and descends into the oil-tank F of said standard for the purpose of conducting oil from the tank F to the receptacle f, substantially as described.

8. The combination of the shell G, whirl D, standard E, and spindle B, whose foot is seated in said standard above the plane of the whirl, substantially as described.

4. The combination, with the spindle B and the shell 0, having whirl D, of the standard E, projecting upward into said shell, said stand ard being provided with an oil-receptacle, F, that receives the lower end of the shell, and an oil-receptacle, f, that receives the lower end of the spindle above the plane of the band-pull of the whirl, the relative position of the said parts being such that an air-cushion is formed in a space, 0, between the shell and upper end of the standard, substantially as described.
